Well I never had any troubles playing even days in a row, and I don't know any professional gamer even who ever had troubles in that direction. Typing is a lot worse ... Hmm. I have no idea

Edit: I have ideas, actually. But firstly, they most likely have nothing to do with what really happened, and secondly, the public-ness of this thread as well as general rules of conduct, etc., ... forbid me elaborate my assumptions.

Didn't Michael Jackson perform with his hand in a bandage once? That was part of his costume, I believe. And PJ carries his injury with so much more dignity and style.

But if he was really injured he is a trooper! Just biting the pain and sing and act anyway! (But carrying the rifle with the wrong hand, I had already noticed that-5 kilo's, hurts)

I saw Joyce diDonato do an opera once in a wheelchair with a broken ankle, that had just happened the day before, poor woman. I don't know what kind of painkillers they had to put her on to get her through that evening.

Well you survive a strained wrist, it just hurts. He's not a sissy, is he ... duh! I don't think it was part of the costume, as it wasn't there in the broadcast, only in the pics for the programme and the PR pics before.

And ofc, Jackson turned wrist-bandages into a trademark-accessoire. Well, what does it convey there? Exactly what you say, I think, as we think of a real injury. Vulnerability, the will and power to overcome hardships, ...

Edit: Di Donato is great in this one!

Hmm, drugged singers, I don't know?

What is similar in a way, and in many ways not at all, of course, was to see Thomas Quasthoff as Amfortas. (You see a brief excerpt there at about 1 min.):
